EMC Test Report
Reference No.: NK08E 683.EMS
12. Fast Transients/Burst (EN 61000-4-4)
12.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
The minimum area of the ground reference plane is 1 m x 1 m, and connected to earth via a low impedance connection.
The EFT/Burst generator was located on the ground reference plane.
The EUT was located 0.1 m above the ground reference plane. The minimum distance between the EUT and all other
conductive structures, except the ground reference plane is more than 0.5 m.
The test voltage was applied simultaneously between each of the power supply conductors and the protective earth at the
power supply.
